Measurement of the Relative Branching Fraction of to Charged and Neutral B-Meson Pairs

J. P. Alexander, CLEO Collaboration

We analyze 9.7 x 10^6 B\bar{B}$ pairs recorded with the CLEO detector to determine the production ratio of charged to neutral B-meson pairs produced at the Y(4S) resonance. We meas…

Precise Measurement of $B^{0}\to \bar{B^{0}$ Mixing Parameters at the S)$

B. H. Behrens, CLEO Collaboration

We describe a measurement of B^0-B^0bar mixing parameters exploiting a method of partial reconstruction of the decay chains B0 -> D^{*-}π^+ and B0 -> D^{*-}ρ^+. Using 9.6 x 10^6 BB…

Study of the Decays B0 --> D(*)+D(*)-

CLEO Collaboration

The decays B0 --> D*+D*-, B0 --> D*+D- and B0 --> D+D- are studied in 9.7 million Y(4S) --> BBbar decays accumulated with the CLEO detector. We determine Br(B0 --> D*+D*-) = (9.9+4…

Search for D0-D0B Mixing

R. Godang, CLEO Collaboration

We report on a search for D0-D0B mixing made by studying the `wrong-sign' process D0->K^+pi^-. The data come from an integrated luminosity of 9.0 1/fb of e^+e^- collisions at s^(1/…
